Case study: 120-panel solar thermodynamic system for Fonterra, Palmerston North

Reducing carbon emissions is essential to avert the worst of climate change, and New Zealand's climate credentials are critical to our exports and economy.

The Alternative Energy Company (TAEC) is proud to be part of Fonterra's decarbonisation journey. At Fonterra's Palmerston North site, our solar thermodynamic hot water system reduces the plant's reliance on natural gas boilers.

In July 2023 Fonterra raised its emissions target to a 50% absolute reduction in Scope 1 and 2 emissions by 2030 from a 2018 baseline, up from its earlier target of 30%. Fonterra has received support through the Government Investment in Decarbonising Industry (GIDI) Fund, which is run by EECA and co-funds businesses to install innovative, energy-efficient technology.

The system

The system is made up of three 40-panel Solar Block units, a total of 120 solar thermodynamic panels. Installation began in September 2023, and the system was commissioned on 19 October 2023.

Solar thermodynamic panels collect heat from the sun and the surrounding air, day and night, so the system keeps working in cloudy weather. Find out more about how solar thermodynamic hot water works, or see our full commercial water heating range.
